What it means for the U.S. to name Jerusalem as Israeli capital but not move the embassy

President Trump is expected to make a major announcement about Jerusalem on Wednesday, potentially upending years of U.S. foreign policy with a move likely to please the Israeli government but deeply anger Arab states and others sympathetic to the Palestinian cause.

The Palestinian, Jordanian and Egyptian governments have said that Trump informed them that he intended to move the U.S. Embassy in Israel from Tel Aviv to Jerusalem, something he pledged to do while on the campaign trail.
